Pearltrees has just updated its app to support the iPhone, after previously being only available on the web and iPad. Pearltrees claims that its service is designed to be something of a hybrid between Pinterest and Evernote. This is designed for people to share their favorite links, photos, and notes into various categories called pearls, the collections of which are known as pearltrees.

Users can track their favorite topics with the app, divided out into varioius sub-topic pearltrees. It’s even possible to collaborate with other users to help curate pearls and pearltrees on their various topics.

The app is also set up to try and let users work even while offline. Loaded pearltrees can be browsed, with notes and photos able to be added, that can then be uploaded once network access has been restored. This could also come in handy for iPod touch users, who don’t even get to worry about the issue of spotty network access! The Pearltrees universal update is available now.
